Abstract

A membrane-type liquefied natural gas (LNG) cargo hold is disclosed. The membrane-type LNG cargo hold comprises one surface which is manufactured by connecting multiple pieces to each other. The pieces are formed by connecting multiple membrane sheets to each other and have corrugations where the corners and ends of the one surface coming in contact with the pieces meet in a vertical direction. The interval between the corrugation ends in the diagonal corners of the one surface is mated with the interval between the corrugation ends in the vertical or horizontal corners of the one surface. Thus, the present invention reduces mold costs as the LNG cargo hold can be manufactured by using a mold.

Description

Membrane Type Liquefied Natural Gas Cargo Containment System [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a membrane-type liquefied natural gas cargo hold, and more particularly, to a membrane-type liquefied natural gas cargo hold which is advantageous in heat deformation and sloshing, and economically.

With growing interest in eco-friendly businesses globally, the demand for clean fuels that can replace existing energy sources such as petroleum and coal is increasing. In this situation, natural gas is used in various fields as a main energy source having cleanliness, stability and convenience. Unlike in the US and Europe, where natural gas is directly supplied through pipelines, Korea is supplying liquefied natural gas (LNG), which is liquefied at extremely low temperatures, to consumers. Therefore, the demand for cargo containment system (CCS) for storing liquefied natural gas is increasing along with the increase of domestic natural gas demand.

Liquefied natural gas is obtained by cooling natural gas to a cryogenic temperature of approximately -163 ° C, and its volume is considerably reduced compared to when it is in a gaseous state, making it well suited for long-distance transport through the sea. Liquefied natural gas carriers are intended to carry liquefied natural gas to the sea and to unload liquefied natural gas to the onshore site, including the cryogenic hold of liquefied natural gas.

Liquefied natural gas cargo holds can be classified as independent tanks and membrane types depending on whether the load of the cargo directly acts on the insulation. Membrane-type cargo holds are divided into GTT NO 96 type and Mark III type, and independent tank type cargo holds are divided into MOSS type and IHI-SPB type. GTT NO 96 and GTT Mark III were formerly called GT type and TGZ type. In 1995, the names of GT (GT) and Technigaz (TGZ) were changed to GTT (Gaztransport & Technigaz) 96 type, and the TGZ type is replaced with the GTT Mark III type.

The membrane sheet constituting the membrane-type cargo hold is formed with a plurality of wrinkles in a transverse direction and a transverse direction so that the membrane sheet can absorb rapid contraction and expansion due to temperature difference.

Figure 1 is a schematic view of a membrane type liquefied natural gas cargo hold, and Figure 2 is a schematic front or rear view of a conventional membrane type liquefied natural gas cargo hold.

2 is a view showing a section of the liquefied natural gas storage window viewed from the inside of the cargo hold, and illustration of the first sealing wall, the first insulating layer, the second sealing wall and the second insulating layer is omitted.

Referring to FIG. 1, the front (1, 10) and rear (2, 20) of a liquefied natural gas cargo hold are generally formed in octagonal shape. Conventionally, the front and rear surfaces (1, 2) , The membrane sheets were connected only in the same direction so that the wrinkles were vertical or horizontal. 2, vertically or horizontally formed edges of the front face 1 and the rear face 2 (for example, portions A in Fig. 2 (hereinafter referred to as "vertical edges" and "horizontal edges" (For example, part B in Fig. 2, hereinafter referred to as "oblique edge") are different from each other.

Specifically, the interior angles of the front and rear surfaces 1 and 2 of the liquefied natural gas cargo holds formed in octagons are generally 135 degrees, so that the corrugation spacing of diagonal corners (for example, the portion B in FIG. 2) Is formed twice wider than the wrinkle interval of the edge (for example, the portion A in Fig. 2).

It is preferable to connect the corrugations of the respective surfaces to each other at corners so that the corrugations formed on the respective surfaces of the liquefied natural gas storage can properly perform the function of absorbing thermal deformation. The upper surface 30, lower surface 40 and both sides 50, 50 of the liquefied natural gas storage window are formed so as to be wider than the corrugation spacing of the vertical corners or horizontal corners (for example, 60 may be made of the same type of mold having the same wrinkle spacing as the mold used for the front face 1 and the back face 2 but it is also possible to use both the upper and lower side faces 70, Has a disadvantage in that it is necessary to use another type of mold having a wrinkle interval that is two times larger than that of the molds used for the front face 1 and the rear face 2. In addition, the use of two kinds of molds has caused problems in terms of economy.
